The one on my Deviate was actually starting to make a dull squeak so that's why it got a birthday today, I have got caught riding what should have been dry trails but came across lots of puddles and trapped water on it about 3 times over the last 6 weeks so reckon that's the cause, it also felt very dry with a buzz on the idler.
I run these YBN SLA on all my bikes now and they are usually very good. I only waxed it and a chain off one of the boys bikes, all others still are feeling good as they have been used dry.
Trying to get the bike 100% ready for Tassie in 3 weeks. Wanting to get everything serviced and well tested so I don't get any surprises.
Race policy thinking, never change, service or adjust stuff on a bike untested the day before an event or trip
